the intention of giving a general resume on all the parts, after we 
have finished our work. Then it will probably be necessary to make 
much change, so as to establish a correct, natural, and philosophic* 
nomenclature. [See note 
Mr. Walsh’s new Gomphus and his descriptions are superb. * 
It is the scourge of science, and especially of Entomology, that we 
have always plenty of dilettantes and but very few with real know¬ 
ledge, based upon regular and truly philosophical study. [>S^ce note 24.] 
STALINA. 
SiALTS INFUMATA Newm. Kightly determined by Mr. Walsh. I 
have it from many places, especially from Saskatchawan. It is very 
desirable that the anal appendages should be figured and described 
from the living specimen. The species of this genus are not easy to 
separate, and I am not sure that infimiata is not synonymous with 
fuliginosa^ a European species ] but on the whole they are probably 
dift'erent. [See note. 25.] 
Chauliodes serrioornis and maculates. There is a confusion 
in the Synopsis, as I was only acquainted with the 9 of serricornis and 
the % of maculatus. I now possess S 9 of both. On comparing Say’s 
description, I find that C. serricorniH Say, is the true C. maculatns, 
and that 0. serrieorni^ Synopsis is a new species. I was partly 
led into the error in consequence of receiving a 9 from Mr. Uhler, 
labelled G. seriHcornis Say. I now view the species as follows :— 
Chauliodes lunatus Hagen. = (7. serricornis Hag. Synop. It is 
the 9 that is described in the Synopsis, but instead of the words 
marked with black,” (p. 191, line 1,) read “ bordered with black”; 
and instead of with white spots,” (line 4,) and “veins spotted, white,” 
(line 7,) read “ bordered with white.” The words “ bordered with 
black” (nigrocinctis) in my work are not altogether correct, for the veins 
are only bordered with a more obscure color. In the more highly 
colored % % the veins are scarcely bordered, for then the black color 
is uniform. The S has foliated antennae, each joint with a large oval 
plate underneath, a structure which Say could never have described 
as “ deeply serrated.” The head and thorax are more slender and 
highly colored than in 9; the design of the wings is the same. It 
may be remarked that the words “ a larger anal spot white” in the
